  • Two-dimensional interpolation architecture for motion compensation in multiple video standards
    Patent number: 8588305
    Abstract: The present invention provides an apparatus for interpolation which is able to process input data with multiple video standards without sacrificing chip area. The interpolation unit comprises: a first interpolation unit for interpolating input data; a second interpolation unit for interpolating input data; a filter indicator for providing information to the first interpolation unit and the second interpolation unit; and an output unit for multiplexing and averaging output from the first interpolation unit and the second interpolation unit. The present invention also provides a motion compensation unit and a decoder for processing multiple video standards.

  • Unified inverse discrete cosine transform (IDCT) microcode processor engine
    Patent number: 8126952
    Abstract: The present invention provides a unified inverse discrete cosine transform (IDCT) microcode processor engine, which is able to process IDCT with different video standards and also achieves the processing speed requirement. The microcode processor engine comprises a read unit for reading input data; a shift left unit comprising: a first shift left block for left-shifting input data; and a second shift left block for left-shifting input data; an add unit for adding data output from the shift left unit; and a shift right unit for right-shifting data output from the add unit. The present invention also provides a system of inverse discrete cosine transform.
